Inventor: YAMASHITA SHINSUKE
IPC: G01N27/06
Filed: 1989-08-21
Abstract: PURPOSE:To enable measurement of concentration by detection of conductivity by making an electrolyte coexist with a nonionic surfactant. CONSTITUTION:A pair of electrodes 10 are charged in a measuring vessel 20 containing ion-exchange water and a liquid W to be measured in the vessel 20 is agitated by an agitator 23. The electrodes 10 are connected with an AC power source device 30 and a miniature bulb 40 and a measuring circuit 50 is constructed of them. When conductivity is measured in a system wherein a small quantity of electrolyte is made to coexist with a nonionic surfactant, hydration of water molecules in the system to the hydrophilic group of the surfactant occurs, the concentration of the electrolyte in bulk water increases relatively, and the resistance of the whole system decreases, while the conductivity increases. By measuring the conductivity after a prescribed amount of electrolyte is added, the concentration of the nonionic surfactant can be known.
